Sorta. You nullify the number before you, and continue from the number before that. So, Post 1=0, Post 2=-1, post 3= 1 BUT ONLY IF IN THE SAME TIMESTAMP! It does not work with two or more posts. Post 1=0, Post 2=-1, post 3= -2, Post 4=1 is invalid. Also, Post 1=0, Post 2=-1, post 3= 1, Post 4=-2 is invalid, even if 2, 3, and 4 are in the same minute, due to only changing one number at a time. If you have other questions about the rules but don't want others to know, ask a GM through a PM! We are more than happy to help.
